Abstract
The utility model provides a chemical heat treatment work piece infiltration layer thickness measurement ware, mainly by lead screw positioning spring, the lead screw, the tail cover, adjusting nut, the lead screw cover, the card head cover, chucking spring, the dop, semicircular nipper etc. constitutes, rotatory adjusting nut and drive lead screw drive measuring stick along the axial slip, the measuring stick makes relative motion with the test bar terminal surface of being centre gripping between dop and semicircular nipper promptly, when the measuring stick top is identical with test bar chemical corrosion circle inner edge, external indicating value instrument indicates the infiltration layer thickness of work piece promptly under the lead screw promotion, this chemical heat treatment work piece infiltration layer thickness measurement ware has simple structure, convenient operation, characteristics such as measurement accuracy is higher.
Description
The utility model is a kind of reflectogauge, refers in particular to the measuring appliance that is used to measure thermo-chemical treatment workpiece alloying layer thickness.
The method of the at present industrial measurement thermo-chemical treatment workpiece alloying layer thickness that generally adopts is: will handle coupon with stove and cut off along the transversal section, through chemical corrosion, grind polishing after, measure its alloying layer thickness by metaloscope.This method measuring accuracy is higher, but it is longer to measure required time, and complex procedures is had relatively high expectations to operator's technical merit and measuring equipment, is difficult to use at medium-sized and small enterprises.
The purpose of this utility model provides a kind of easy to carry, and is simple to operate, and measuring accuracy is higher, and measuring speed is fast, the thermo-chemical treatment workpiece alloying layer thickness measuring appliance of being convenient to operate at the construction field (site).
Below in conjunction with accompanying drawing the utility model is described.
Fig. 1 is a main cut-open view of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Referring to accompanying drawing 1, Fig. 2, the utility model is by dog screw 1,6,13,14,17,18, screw mandrel retainer spring 2, screw mandrel 3, tail cover 4, adjusting nut 5, screw rod bushing 7, guide finger 8, dop cover 9, garter spring 10, dop 11, half garden clamp plate 12, measuring stick 15, baffle plate 16, magnifying glass 19 formations such as grade, one end of described dop cover 9 has half garden shape step, one side of step has a rectangular channel, opposite side is that rectangular bottom, top is that the half ellipse garden shape tangent planes that dop cover 9 forms are cut on an inclined-plane, and the center of dop cover 9 is drilled with through hole that diameter do not wait and formation one step in the hole; Half garden shape step end face of dop cover 9 is fixed with half garden clamp plate 12 by dog screw 13,14, is fixed with magnifying glass 19 in the side of step by screw; Being set with successively an end in the centre bore of dop cover 9 is the V-type mouth,, the other end is provided with the dop 11 that garden shape boss, center are drilled with through hole, garter spring 10, baffle plate 16 with central through hole, and an end is provided with axially directed groove, the other end is the screw rod bushing 7 that symmetrical garden arc boss, center are drilled with through hole; Dop 11 contacts the location with its garden shape boss with step in dop overlaps 9 central through holes, and screw rod bushing 7 is positioned in the dop cover 9 by its symmetrical garden arc boss, is linked to each other by dog screw 17 and dop cover 9, and makes baffle plate 16 push garter springs 10 and jam-packed dop 11; Screw mandrel 3 is sleeved in the screw rod bushing 7, and the measuring stick 15 that is fixed on screw mandrel 3 one ends can pass the centre bore of the centre bore of baffle plate 16 and garter spring 10 and dop 11 and extend to the bottom surface of half garden clamp plate 12; The guide finger 8 that arranges in screw mandrel 3 sides can be with screw mandrel 3 at axial gathering sill slip certain distance along screw rod bushing 7; The middle part of screw mandrel 3 is provided with screw thread, and adjusting nut 5 spins on it and contacts with the outer face of screw rod bushing 7; The other end of screw mandrel 3 is sleeved in the central through hole of tailstock 4, and is positioned in tailstock 4 centre bores on the step by an end, screw mandrel retainer spring 2 location of the other end and screw mandrel 3 end contacts; Tailstock 4 is fixed on the symmetrical garden arc boss of screw rod bushing 7 by dog screw 6,18; Also be provided with for the fixing dog screw 1 of indicating value instrument at an end of tailstock 4.
Of the present utility model all zero, parts all can adopt normal carbon steel making, chrome-faced; According to the needs that measurement category changes, can make series of products.
Using method of the present utility model is:
1. adjust: at first adjust setting nut 5, the top of sounding rod 15 is contacted with the bottom surface of half garden clamp plate 12, the indicating value instrument that will return to zero then is connected on the afterbody of tailstock 4 and fixes with dog screw 1.
2. measure: depress that dop 11 will cut off along the transversal section and be clipped between dop 11 and the nipper 12 through the coupon of chemistry, rotation setting nut 5 is till the corrosion of sounding rod top and coupon is enclosed inner edge and matched, at this moment, indicating value instrument indication is the workpiece alloying layer thickness.Thereby realize the purpose of stokehold fast measuring thermo-chemical treatment surface of the work alloying layer thickness.
The utility model is adapted to the mensuration of various thermo-chemical treatment surface of the work alloying layer thicknesses, and its precision is higher; Simple to operate, maintenance, easy maintenance help improving the thermo-chemical treatment quality.
